Abstract
A battery-powered hand-tool, such as a battery-powered drill, battery-powered screwdriver or the like, has a tool mechanism housing, advantageously having a connected handle in one piece with the tool mechanism housing, a battery housing and an effective locking connection device for locking the battery housing together with the tool mechanism housing. The locking connection device has lock elements on the tool mechanism housing, which engage under suitable lock catches on opposite side walls of the battery housing. To provide a simplified structure for the lock connection device which permits an easy and economical manufacture of the hand-tool, the lock elements include a resilient U-shaped clasp member mounted on tool mechanism housing. The lock catches engage over both U-legs in the locked state of the locking connection means.
